Underground gravity heat pipe direct heating device

Abstract

The invention provides an underground gravity heat pipe direct heating device. A decorative protection cover of the heating device is connected to aluminum wing type cooling fins through screws. The aluminum wing type cooling fins are connected to peripheries of cooling branch pipes in a sleeving manner. Each cooling branch pipe is connected to and communicates with a horizontal mother pipe. The horizontal mother pipe is connected to the heat insulation section of an underground gravity heat pipe through a tee joint. A liquid injection opening is connected to one end of the tee joint. The underground gravity heat pipe direct heating device has the beneficial effect that geothermal energy is sufficiently used through the underground gravity heat pipe direct heating device. In the construction heating energy consumption, the conventional energy consumption can be partially or completely replaced, and energy conservation of 20%-30% can be achieved through partial replacement; and conventional energy can even be completely replaced in some places with low requirements for the room temperature. The automatic one-way heat transfer characteristic of the gravity heat pipe is used, no movement parts are used, and manual operation is not needed during operation. The device is particularly suitable for on-duty heating systems of industrial buildings, and has the beneficial effects that energy conservation is achieved and no operating cost is generated.

Description

technical field

[0001] The invention relates to a heating device, in particular to an underground gravity heat pipe direct heating device. Background technique

[0002] At present, the existing heating technology still mainly relies on conventional energy, but the consumption of conventional energy has aggravated environmental pollution and caused many problems. Therefore, rational use of new energy such as geothermal energy is an inevitable choice.

[0003] At present, there is no technology of using buried gravity heat pipes to directly heat radiators, but using buried gravity heat pipes to directly heat radiators for low-temperature heating rooms that do not require high room temperature can improve the utilization rate of geothermal energy and reduce the consumption of conventional energy. Consumption, in line with the requirements of social energy-saving development.
